Synchronous Motor : Working Principle, Types, and

03/06/2019  Synchronous Motor. The synchronous motor doesn’t rely on induction current for working. In these motors, unlike induction motor, multiphase AC electromagnets are present on the stator, which produces a rotating magnetic- field.Here rotor is of a permanent magnet which gets synced with the rotating magnetic- field and rotates in synchronous to the frequency of current applied to it.
